Narrative:
I had previously written up a complaint that the aircraft's engine instrument lights were inoperative. I noted the next day that the problem had been fixed and the mechanics had replaced all of the engine instruments. After takeoff and return to the base, I realized that the 'something isn't right feeling' was due to the fact the turbine outlet temperature gauge markings were incorrect. I reported the incident to maintenance and my supervisor. In the future, during preflight, I will be more cautious about looking at the ranges of the instruments during preflight.

Narrative: I HAD PREVIOUSLY WRITTEN UP A COMPLAINT THAT THE ACFT'S ENG INST LIGHTS WERE INOP. I NOTED THE NEXT DAY THAT THE PROB HAD BEEN FIXED AND THE MECHS HAD REPLACED ALL OF THE ENG INSTS. AFTER TKOF AND RETURN TO THE BASE, I REALIZED THAT THE 'SOMETHING ISN'T RIGHT FEELING' WAS DUE TO THE FACT THE TURBINE OUTLET TEMP GAUGE MARKINGS WERE INCORRECT. I RPTED THE INCIDENT TO MAINT AND MY SUPVR. IN THE FUTURE, DURING PREFLT, I WILL BE MORE CAUTIOUS ABOUT LOOKING AT THE RANGES OF THE INSTS DURING PREFLT.
